Trying to run Waveshare 7'' display on my Pi4. According to Waveshare manual I should set params manually in config.txt:

[all]
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
hdmi_drive=1

Unfortunately I can't see whole screen. Only top, bottom and left side is visible. Touchscreen is hitched. When I press most top left corner few centimeters down and few centimeters right is affected.

How to solve this problem?

When I connect the same display to Pi3 everything goes fine.
